When using the Debug in connector P18 to program the on board NRF52 chip U1 from an external programmer, do I need to cut the joining track on SB20,SB21 & SB27 to isolate U2 from U1 in the NRF52DK

Hi Anders, you reference a video in your blog but did not provide a link (please can you add this)??

I did find a video on youtube https://www.youtube.com/watch?v=3xilrdYBwwg that I gusee kind of gives me an idea -

Anantha Keshava this may help you with the required connections to tell the JLink programmer to target an external micro

In order to get someone going with the External Debugger, it'll be great if you could show interfacing the nRF5x DK with say a JLINK debug interface by disabling the OB JTAG.

Wonder if the on-board debug chip on the nRF52840-DK has the trace capability ?

The headers are described in the Schematic included in the nRF51 DK hardware files

I'd like to use the P20 headers, I don't know which pin header to use to interface with my external board, I mean which four pins to use form the header file ? ?
